Abstract
A method and apparatus for logging write requests to a storage volume in a network data switch is described. In one example, a switch component in a switch receives a write request from a host server. The write request is associated with a destination in the storage volume. A logging element is identified that is associated with the destination of the write request. The logging element may be a switch component in the switch (e.g., a virtualization card), or may be dedicated logging circuitry in the switch. The identified logging element then logs a write intent for the destination in a log.
